A newly discovered mechanism could explain the shock finding last year that oxygen is produced by metallic nodules on the ...

At some point, iron within rocks on Mars reacted with water or water and oxygen in the air, creating iron oxide — much in the same way rust forms on Earth. Over billions of years, the iron oxide ...

"Our study reveals that ferrihydrite formation on Mars required the presence of both oxygen – whether from the atmosphere or other sources – and water capable of reacting with iron. These ...

Electrolysis has been a mainstay of crewed mission designs for the outer solar system for decades. It is the most commonly ...

NASA's Perseverance rover, which has been exploring Mars since 2021, fired its laser at some oddly pale rocks on the surface ...

That is, iron bound up in the chemistry of Mars’s rocks has at some point reacted with water and oxygen in some form, just like everyday rust forms on Earth. Over billions of years this rusty ...

Mars' atmosphere moves differently from Earth's due to gravity waves. These waves affect air circulation at high altitudes.

That is, iron bound up in Mars's rocks has at some point reacted with liquid water, or water and oxygen in the air, similar to how rust forms on Earth. Over billions of years, this rusty material ...
